If a bag contains 3 red, 4 green, and 5 white marbles, then the probability that a green marble will be selected in the first attempt is equal to 4/12 or 1/3.

Probability is defined as the likeliness of an event to happen. It simply means possibility of any event to occur or the possibility of an event to not occur. The sum of the possibilities in any event is always equal to one. In the given case, there are 3 red, 4 green, and 5 white marbles.

Now total number of marbles is equal to 3+4+5 = 12 marbles

Probability that the green marble is picked first = 4/12 = 1/3

Probability that Harry, Jason, and Sarah will get admissions to their desired schools given that they study independently and the admissions are independent of one another is 0.0088 or approximately 0.9%.

The probability of Harry, Jason, and Sarah getting admission to their desired schools is the probability that Harry's score is above 650, Jason's score is above 630, and Sarah's score is above 670. The scores on the GMAT are roughly normally distributed with a mean of 550 and a standard deviation of 115.So, let's first standardize Harry's score:Z = (650 - 550) / 115 = 0.87Similarly, for Jason's score:Z = (630 - 550) / 115 = 0.70And for Sarah's score:Z = (670 - 550) / 115 = 1.04Now we need to find the probabilities of getting each of these Z-values. We can do that using the standard normal distribution table. The table gives the probability that a standard normal random variable is less than or equal to a certain Z-value.To find the probability that Harry's score is above 650, we need to find the probability that Z > 0.87. This can be found by subtracting the probability of Z ≤ 0.87 from 1:P(Z > 0.87) = 1 - P(Z ≤ 0.87) = 1 - 0.8078 = 0.1922Similarly, the probability that Jason's score is above 630 is:P(Z > 0.70) = 1 - P(Z ≤ 0.70) = 1 - 0.7580 = 0.2420And the probability that Sarah's score is above 670 is:P(Z > 1.04) = 1 - P(Z ≤ 1.04) = 1 - 0.8508 = 0.1492The probability that all three events occur (Harry's score is above 650, Jason's score is above 630, and Sarah's score is above 670) is the product of their probabilities:P(Harry, Jason, and Sarah) = P(Z > 0.87) × P(Z > 0.70) × P(Z > 1.04) = 0.1922 × 0.2420 × 0.1492 = 0.0088Therefore, the probability that Harry, Jason, and Sarah will get admissions to their desired schools given that they study independently and the admissions are independent of one another is 0.0088 or approximately 0.9%.

Answer: x = π - π/4 = 3π/4

Step-by-step explanation:

If sec(x) = -√2 and x is in the second quadrant (between π/2 and π), we can use the identity:

sec^2(x) - 1 = tan^2(x)

to find the value of tan(x):

sec^2(x) - 1 = tan^2(x)

(-√2)^2 - 1 = tan^2(x)

2 - 1 = tan^2(x)

1 = tan^2(x)

Taking the square root of both sides, we get:

tan(x) = ±1

Since x is in the second quadrant, the angle that satisfies tan(x) = 1 is π/4. Therefore, we have:

x = π - π/4 = 3π/4

Note that the angle that satisfies tan(x) = -1 is in the fourth quadrant, so it is not relevant to this problem.

Answer:

The answer you're looking for is x = 6, and the missing angle is 30º

Step-by-step explanation:

In order to find the answer we need to find out what the angle amount actually is. We can use the equation 180º = 110+ 40 + (8x-18).

Now there are two ways to solve this equation you could solve it by starting with the equation actually is or you can find out the missing angle using another equation.

First Method:

Using 180º = 110+ 40 + (8x-18), you first need to do is to combine like terms such as combining 110, 40, and -18, giving you 132.

Now you have 180 = 132 + 8x.

Then you will have to make sure that 8x is left by itself so do the opposite operation and to keep the equation balanced you do it on both sides giving you 48 = 8x. The only step left to do is to do the opposite operation on both sides which is dividing by 8, giving you 6 = x

Now with that, you replace x, with 6, and go from there.
(8x-18) = (8×6-18) = (48 - 18) = 30.

With that, we are finished with the equation.

However, the other method you could use, which is easier in my opinion, can be found below.

Second Method:

The first thing we do is find out immediately what the missing angle (m) is using the equation 180 = 110 + 40 + m.

You combine like terms 110 and 40, giving 150 and then get,
180 = 150 + m.

You then do the inverse of operations, which is subtracting 150 from both sides and you get 30 = m.

Now that we complete that we start with our other equation which is:
30 = 8x-18. You then do inverse of -18, which adds 18 to both sides giving: 48 = 8x.

Finally doing the inverse operation of multiplying is dividing 8 by both sides giving 6 = x as the correct answer.

The equation correctly relates the total cost y to rent the washer for x days is option (B) Y = 40 + 20x

The rental fee of $40 is charged regardless of the number of days the power washer is rented. In addition to this fee, there is a daily charge of $20 per day.

Therefore, the total cost of renting the power washer for x days can be calculated by multiplying the daily charge by the number of days rented and adding the rental fee:

Total cost = (daily charge) x (number of days rented) + rental fee

Total cost = $20x + $40

This linear equation can be rearranged to the form:

Y = 40 + 20x

Therefore, the correct option is (B) Y = 40 + 20x

Answer:

$150

Step-by-step explanation:

Interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the interest rate, and Time is the duration of the loan.

In this case, the Principal is $1,000, the Rate is 10%, and the Time is 18 months (which we'll convert to a fraction of a year).

First, we need to convert 18 months to a fraction of a year. Since there are 12 months in a year, 18 months is equal to 18/12 = 1.5 years.

Using the formula:

Interest = Principal x Rate x Time

Interest = $1,000 x 0.10 x 1.5

Interest = $150

So the interest on the $1,000 loan with a 10% simple interest rate for 18 months is $150.

Answer:

The formula for simple interest is I = Prt, where I is the interest, P is the principal or amount borrowed, r is the interest rate, and t is the time in years.

In this case, P = $1,000, r = 10% or 0.10 as a decimal, and t = 1.5 years (since 18 months is equivalent to 1.5 years).

I = Prt

I = $1,000 * 0.10 * 1.5

I = $150

Therefore, the interest on the $1,000 loan with a 10% simple interest rate for 18 months is $150.

The area of the sector is evaluated to be equal to 9π square meters

The area of a sector is calculated by multiplying the fraction of the angle for the sector divided by 360° and πr², where r is the radius.

For the area of circle 72π m²;

πr² = 72π m²

r² = 72 m²

hence the area of the sector is calculated as follows:

area of the sector = (45°/360°) × π × 72 m²

we simplify by multiplication and division

area of the sector = 1/8 × π × 72 m²

area of the sector = π × 9 m²

area of the sector = 9π m².

Therefore, the area of the sector is evaluated to be equal to 9π square meters

As a result, the answer to the following question, As a result, the supplied radius arc's arc length is roughly 6.91 inches (rounded to nearest hundredth).

In more modern use, the length of a sphere or sphere is equal to its radius in standard geometric, so it has several line segments from its centre to its circumference. The phrase is derived from the Latin word for radius, which also referred to the spokes of a waggon wheel. The radius of a circle is the distance between the centre and any point on its periphery. Often, "R" or "r" is used to signify it. A radius is a boundary line with one terminus in the centre and a second around the perimeter of a circle. Vide letter diameter equals radius The dimension of a circle is the segment that passes its centre and has extremities that are on the circle.

The formula for calculating the arc length of a circle is:

Arc length = radius x central angle in radians,

In order to use this formula, we must first convert the centre angle from degrees to radians. We are aware of the following:

2 radians Equals 360 degrees

360 degrees divided by 2 radians equals x degrees divided by y radians

(x degrees * 2 radians) / 360 degrees = y

y = (22 deg * 2 radians) / 360 deg = 0.38397 deg (rounded to five decimal places)

arc length Equals radius multiplied by Centre angle in radians

With r = 18 inches and = 0.38397 radians, we get:

arc length = 18 inches multiplied by 0.38397 equals 6.9115 inches (rounded to four decimal places)

As a result, the supplied arc's arc length is roughly 6.91 inches (rounded to nearest hundredth).

Using the equation C(x) = 120(0.88)ˣ, we found that after 19.27 hours, the amount of caffeine becomes 10mg.

What is meant by an equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

Given,

The initial amount of caffeine in the beverage = 120 mg

The rate at which the caffeine decreases = 12% per hour w

We are asked to find the time taken for the caffeine amount to become 10mg.

Now let the initial amount be 100 per cent.

After one hour, the amount becomes (100-12)  = 88% of 120 = 0.88 * 120

So after every one hour, there is 88% caffeine left.

Now after two hours,

the amount of caffeine = 88% of (0.88*120) = 0.88*0.88*120 = 120(0.88)²

So after x hours, we can write the equation as:

Amount of caffeine left C(x) = 120(0.88)ˣ

Now for 10mg to be left, the time taken is:

10 = 120(0.88)ˣ

1/12 = (0.88)ˣ

log (1/12) = x log(0.88)

-1.079 = x (-0.056)

x = 19.27 hours

Therefore using the equation C(x) = 120(0.88)ˣ, we found that after 19.27 hours, the amount of caffeine becomes 10mg.

The missing coefficients in the equation y = mx + b are m = 0.841 and b = 18.813. The final equation that fits the given data is y = 0.841x + 18.813

To find the missing coefficients in the equation y = mx + b, we need to use the given data in the table to determine the values of m and b.

We can start by using two of the data points to set up a system of equations:

Using (5, 23.018) and (6, 23.859):

m(5) + b = 23.018

m(6) + b = 23.859

Subtracting the first equation from the second equation gives:

m(6) - m(5) = 0.841

Simplifying this expression:

m = 0.841 / (6 - 5) = 0.841

Now we can substitute the value of m into one of the original equations to solve for b:

m(5) + b = 23.018

0.841(5) + b = 23.018

b = 23.018 - 4.205

b = 18.813
